Sounds like your running out of fuel to me. Your fuel pressure at wot should be around 2100 to 2200.

get a datalog of a wot pull and we can tell you exactly what's wrong. the last time i had that same CEL; i had 40% ethanol mixed in the tank and the car ran out of high pressure fuel.
the datalog will tell you exactly where the problem is best of luck; before putting the car into limp mode again; find out what exactly the problem is and address it

If you use the tune from Whipple, check the desired fuel pressure. It usually makes the trouble. I had the same issue.
